1. 计算：
(1) $[\frac{5}{4} - \frac{1}{3} + (-2)^3 × (-\frac{1}{2})^2] × (-12)$；
(2) $(-4)^2 ÷ (-1\frac{3}{5}) - \frac{5}{6} × [(-\frac{3}{4}) - (-\frac{1}{2})^2]$；
(3) $-1 - [1 - (1 - \frac{1}{6})] × [5^2 - (-3)^2]$；
(4) $-2^3 - [(-3)^2 - 2^2 × \frac{1}{4} - 8.5] ÷ (-\frac{1}{2})^2$；
(5) $-32 - \left|(-5)^3\right| × (-\frac{2}{5})^2 - 18 ÷ \left|-(-3)^2\right|$；
(6) $-1 - \{ (-3)^3 - [3 + \frac{2}{3} × (-1\frac{1}{2})] ÷ (-2) \}$。

(1) $13$
(2) $-9\frac{1}{6}$
(3) $-\frac{11}{3}$
(4) $-6$
(5) $-54$
(6) $25$

2. 计算：$\left| -( -\dfrac{2}{3} )^2 + ( -\dfrac{5}{9} ) \right| - 2.45 × 8 + 2.55 × (-8)$

$-39$
